12Vdc Input: 2.1A USB Charger for Smart Phones and Tablets Reference Design
Description
This reference design takes a 12Vdc input (20V max) and generates a 5V/2.1A output for charging smart phone and tablets. The TPS54240 provides a cost effective yet efficient solution for the DC/DC conversion. The TPS2561A provides a precision current limit to protect the device being charged during over load conditions. The CSD25302 provides a gated latch that protects against output over-voltage conditions.
